What are the formulas of series connection?

Answer 1

The following rules apply to a parallel circuit:

1. The potential drops of each branch equals the potential rise of the source.
2. The total current is equal to the sum of the currents in the branches.
3. The inverse of the total resistance of the circuit (also called effective resistance) is equal to the sum of the inverses of the individual resistances.

   One important thing to notice from this last equation is that the more branches you add to a parallel circuit (the more things you plug in) the lower the total resistance becomes. Remember that as the total resistance decreases, the total current increases. So, the more things you plug in, the more current has to flow through the wiring in the wall. That's why plugging too many things in to one electrical outlet can create a real fire hazard.

Answer 2

we can connect number of elements in the series connection in the circuit.in series connection one element of positive terminal is connected to the negative terminal of another element.this is the way of series connection in a circuit.

Answer 3

That depends on the design of the circuit, what information is given, and what you want to figure out.

One common calculation is that you have two or more resistors in series, and you want to calculate the equivalent resistance. In that case, you just add all the individual resistance values. As a formula:

R = R1 + R2 + R3 ...

Where "R" is the combined (equivalent) resistance, and R1, R2, etc. are the individual resistance values.
